It's not the king pin. That is nice and tight. There is only movement on the hub when I spin it. At first I thought it was small enough to ignore until I put the wheel/tire on and spun that. It was definitely amplified. Both hubs had the problem, but the drivers side seamed to be worse, even when swapping. That is confusing, so I just took them in and let the shop take a look to see if the inner bearings and roundness is good.
